I'm looking for pool shock to sanitize my drinking water. Will this work?
Reply
I have heard of people using pool shock to sanitize drinking water but I can not promote the use of any pool shock for this purpose. You will want to contact the NSF for further information.

My water is turning green. I had my water tested and it shows 5 on the total chlorine and 0 on the free chlorine, what can I do?
Reply
Chlorine in water may be present in two forms, free and combined. Free chlorine does the hard work of killing bacteria and oxidizing contaminants. When you add chlorine to water, you are actually adding free chlorine. When the free chlorine combines with contaminants, it becomes combined chlorine, or chloramines. This form of chlorine has very little sanitizing ability, and no oxidizing ability. Total chlorine is just the sum of both combined chlorine and free chlorine. You may have what is considered chlorine lock. Chlorine lock can occur in swimming pools where the chlorine in the pool is rendered inactive, even though you may have a total chlorine reading in the pool. In essence, a chlorine “block” means that the chlorine in the pool is literally being blocked from doing its job by other chemicals. The quickest way to resolve a chlorine lock issue is to partially drain and refill the pool.

Can I add shock through my automatic chlorinator?
Reply
No, you should never add shock through an automatic chlorinator. Never mix different types of chlorine. Pool shock can be added to a bucket of water and poured directly into the swimming pool.

I have an in ground pool with a mesh winter cover. Several weeks ago, I had added 2 gallons of chlorine to the pool. Since then, with the mesh cover still on, the water has turned green. I've been adding about a gallon of shock each week without improvement. Should I continue adding shock to the pool or should I wait?
Reply
I would recommend waiting until the pump and filter are running again before adding any more shock to the pool. Algae needs two things to grow: food and light. With a mesh winter cover, the algae has more than enough light to grow regardless of the shock that you're putting in. Also, shocking the pool without circulation can cause bleaching of the pool surface

My pool company recommends using a phosphate remover. Do you have any such item?

Reviewed By: Robert R. from San Diego, CA ()
Pros: water clarity
My personal standard for water clarity is my dime test. I have a dime epoxied to the bottom of the deep end of the pool. If I can clearly see the face on the dime, then the water is clear. Zappit Pool Shock gets the job done using less shock than other brands. Costs less, too.
